100% renewable electricity: A classic kiwi stoush in the making - Planetary Ecology

Robert McLachlan Mar 28, 2019

That’s the title of the new report from Simon Upton, Parliamentary Commissioner for the Environment. In a pattern we’ve become used to, James Shaw, Minister for Climate Change, immediately released a statement to say that the report’s main recommendation – that forests not be allowed to offset fossil emissions – was not on the table.
